Nothing like a fun day at the ball park on a family Sunday! Britney Spears and boyfriend Jason Trawick headed out to root on her son Sean Preston Federline at his Little League game in L.A. on Sunday, along with dad Kevin Federline and his fiancee, Victoria Prince, and Sean’s little brother Jayden James. Quite the familial gathering! Brit even held a fellow fan’s baby in her lap during the game!
